[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Embodiment 1:

[0023] Please refer to the attached Figure 1-2 The utility model provides a diffusion dust removal device for clay sand processing, including a cylinder 1. It should be noted that the cylinder 1 is the shell of a diffusion cyclone dust collector for clay sand processing. The diffusion cyclone dust collector is a well-known technology for those skilled in the art. The top of the side of the cylinder 1 is fixedly connected with an air inlet pipe 2. It should be noted that the air inlet pipe 2 is tangent to the cylinder 1, and the top center of the cylinder 1 is fixedly connected with an air outlet pipe 3. A conical hopper 4 is arranged at the bottom of the cylinder 1, and a plurality of brackets 5 are vertically fixed at the top edge of the hopper 4. The bottom of the hopper 4 is fixedly connected to the bottom of the hopper 4. There is a dust discharge pipe 6, that is, the dust-containing gas enters the cylinder 1 from the air inlet pipe 2. Since the air inlet pipe 2 is tangent to the cylinder 1 to form a volute shape, the dust-containing gas entering the cylinder 1 forms a downward rotating external vortex flow, so that the dust suspended in the external vortex flow hits the cylinder wall of the cylinder 1 under the action of centrifugal force, and is transferred to the bottom of the hopper 4 with the external vortex flow. The purified gas forms an ascending internal vortex flow and is discharged through the air outlet pipe 3. A dust discharge assembly is fixed at the bottom of the hopper 4, and a cleaning assembly for scraping the inner wall of the hopper 4 is fixed on the dust discharge assembly. A vibration assembly is also fixed on the side of the hopper 4;

[0024] The dust discharge component is a servo motor 7, which is vertically fixed at the bottom of the hopper 4. The top of the output shaft of the servo motor 7 vertically passes through the bottom of the hopper 4, and a feeding screw 8 is fixed to the top of the output shaft of the servo motor 7. Specifically, when the servo motor 7 is running, it can drive the feeding screw 8 to rotate, so that the dust flowing into the hopper 4 can be transported downward and then discharged through the dust discharge pipe 6, that is, the dust can be cleaned without stopping the machine;

[0025] The cleaning component is a connecting shaft 9 vertically arranged in the hopper 4, and the bottom end of the connecting shaft 9 is fixed to the top of the feeding screw 8, that is, the connecting shaft 9 can rotate synchronously with the feeding screw 8, and a plurality of connecting rods 10 are fixed to the top of the connecting shaft 9 in a circular array, and a scraper 11 is fixed to the end of the connecting rod 10 away from the connecting shaft 9, and a rubber scraper 12 is fixed to the surface of the scraper 11. The rubber scraper 12 is preferably set to a silicone material, and the surface of the rubber scraper 12 is in contact with the side of the inner wall of the hopper 4. Specifically, when the servo motor 7 drives the feeding screw 8 to rotate, it can synchronously drive the connecting shaft 9 to rotate in the hopper 4, so that the scraper 11 is driven to rotate in the hopper 4 through the connecting rod 10, so that the rubber scraper 12 can scrape the side of the inner wall of the hopper 4, thereby effectively cleaning the dust adhering to the inner wall of the hopper 4;

[0026] The vibration component is a plurality of electromagnetic exciters 13. It should be noted that the electromagnetic exciter is a device that generates vibrations through electromagnetic force. It is mainly composed of an electromagnetic coil, an iron core and a vibrating device. The working principle of the electromagnetic exciter is to use electric current to generate a magnetic field in the electromagnetic coil. When the current passes through the coil, the iron core around the coil will be affected by the magnetic field and become magnetized, thereby exciting the vibrating device to vibrate. A plurality of electromagnetic exciters 13 are fixed in a circular array on the outer surface of the hopper 4. Specifically, when the electromagnetic exciter 13 is running, a vibration force can be generated at the hopper 4, which can reduce dust adhesion by vibration, and is conducive to thorough dust discharge.

[0027] It should be noted that the device is electrically connected to an external main controller and 220V mains electricity, and the main controller can be a computer or other prior art equipment for control.

[0028] The use process of the utility model is as follows: the dust-containing gas enters the cylinder 1 from the air inlet pipe 2. Since the air inlet pipe 2 is tangent to the cylinder 1 to form a volute shape, the dust-containing gas entering the cylinder 1 forms a downward rotating external vortex, so that the dust suspended in the external vortex hits the cylinder wall of the cylinder 1 under the action of centrifugal force, and is transferred to the bottom of the hopper 4 with the external vortex. The purified gas forms an ascending internal vortex and is discharged through the air outlet pipe 3. When the servo motor 7 is running, it can drive the feeding screw 8 to rotate, so that the dust flowing into the hopper 4 can be transported downward, and then discharged through the dust discharge The dust is discharged through the outlet pipe 6, that is, the dust can be cleaned without stopping the machine. When the servo motor 7 drives the feeding screw 8 to rotate, it can synchronously drive the connecting shaft 9 to rotate in the hopper 4, thereby driving the scraper 11 to rotate in the hopper 4 through the connecting rod 10, so that the rubber scraper 12 can scrape the side of the inner wall of the hopper 4, thereby effectively cleaning the dust adhering to the inner wall of the hopper 4. When the electromagnetic exciter 13 is running, it can generate vibration force at the hopper 4, that is, reduce dust adhesion by vibration, which is conducive to the thorough discharge of dust.

[0031] The use process of the utility model is as follows: the dust-containing gas enters the cylinder 1 from the air inlet pipe 2. Since the air inlet pipe 2 is tangent to the cylinder 1 to form a volute shape, the dust-containing gas entering the cylinder 1 forms a downward rotating external vortex, so that the dust suspended in the external vortex hits the cylinder wall of the cylinder 1 under the action of centrifugal force, and goes to the bottom of the hopper 4 with the external vortex. The purified gas forms an ascending internal vortex and is discharged through the air outlet pipe 3. When the servo motor 7 is running, it can drive the feeding screw 8 to rotate, so that the dust flowing into the hopper 4 can be transported downward and then discharged through the dust discharge pipe 6, that is, there is no need The dust can be cleaned when the machine is stopped. When the servo motor 7 drives the feeding screw 8 to rotate, it can synchronously drive the connecting shaft 9 to rotate in the hopper 4, thereby driving the scraper 11 to rotate in the hopper 4 through the connecting rod 10, so that the rubber scraper 12 can scrape the side of the inner wall of the hopper 4, thereby effectively cleaning the dust adhering to the inner wall of the hopper 4. When the electric push rod 15 is running, it can drive the hammer head 16 to move back and forth, so that the hopper 4 can be intermittently hammered to generate vibration, which can reduce dust adhesion by vibration, which is conducive to thorough dust discharge.
